Phosphotyrosine-binding domains, typified by the SH2 (Src homology 2) and PTB domains, are critical upstream components of signal transduction pathways. The E3 ubiquitin ligase Hakai targets tyrosine-phosphorylated E-cadherin via an uncharacterized domain. In this study, the crystal structure of Hakai (amino acids 106-206) revealed that it forms an(More)
Sprouty proteins are involved in organogenesis, particularly during the branching of endothelial tubes, and existing evidence suggests that Sprouty's point of action lies downstream of receptor signaling to inhibit the activation of the central Ras/Erk pathway. How Sprouty proteins accomplish their inhibitory action and whether they interact with other(More)
The Sprouty (Spry) proteins act as inhibitors of the Ras/ERK pathway downstream of receptor tyrosine kinases. In this study, we report a novel interaction between protein kinase C delta (PKCdelta) and Spry2. Endogenous PKCdelta and Spry2 interact in cells upon basic fibroblast growth factor stimulation, indicating a physiological relevance for the(More)
Extracellular regulated kinase 5 (ERK5) is an unusually large member of the MAP kinase family of signaling molecules that plays an important role in cellular proliferation, differentiation and survival. Recently, three transcriptional variants of murine Erk5 were described (mErk5-a, -b and -c) that result from alternate splicing across introns 1 and/or 2,(More)
Dengue Virus (DENV) infection is responsible for the world's most significant insect-borne viral disease. Despite an increasing global impact, there are neither prophylactic nor therapeutic options available for the effective treatment of DENV infection. An attractive target for antiviral drugs is the virally encoded trypsin-like serine protease (NS3pro)(More)
